I tried to change my engine size got a letter back saying I need proof of purchase of the engine to prove it wasn't stolen and a engineers report saying it been installed safely. So thought stuff it and didn't both to change it. It's insured correctly and never had any issues since
In tank swirl pot and pump, the range rover one is fine and can be made considerably shorter than standard without any issues. Mines in a GBS zero which has a small size tank and had a stupid angle at the bottom of the tank which the robin hood doesn't so I made a tank extension with locking collar. The pump can be easily be swapped out for a high performance unit if you want to go bigger power down the line.
Brilliant weekend and lovely setting. Hopefully this will become a yearly thing again now COVID lockdowns have finished. Craig and his family have been great host and can't thank everyone who made the weekend what is was enough.
